Yanmar releases world's smallest marine common-rail diesel engine and joystick

While all the talk in 2018 has thus far centred on new outboard engines, Yanmar has launched the world's smallest common-rail inboard marine diesel engine, a higher horsepower diesel duo in its mid-range series, and an expansion of its joystick range.

The trio of new releases at the recent round of big boat shows from Europe to Miami will appeal to a vast range of boaters — from those with small yachts and cruising catamarans hankering for a new-age frugal and fume-free power solution to sportfishers wanting low-down fish-hauling grunt and pleasure boaters seeking easy docking solutions.

YANMAR 3JH40
Launched at boot Düsseldorf in January, the latest addition to Yanmar's family of new generation common rail (CR) diesel engines is a compact 3JH40 that is in fact the smallest marine common-rail diesel engine on the market today.

With an output of 40mhp, the 3JH40 will enable a whole new category of smaller leisure boat-owners and commercial vessel operators to benefit from the efficiency and performance advantages associated with electronically-managed CR fuel-injection technology.

With minimal fuel consumption and, says Yanmar, exceptionally low noise and emission levels, the new 3JH40 propulsion engine surpasses EPA Tier 3 and EU RCD Tier 2 emission regulations for virtually smoke and odour-free operation.

The four-stroke, water-cooled 3JH40 is being marketed as an ideal solution for new builds and repowering applications, specifically monohull sailing yachts and catamarans up to 45ft, small motor boats or sloops, and light duty commercial craft.

Weighing 192 kg and with 1.642lt displacement, the engine can be operated by either standard mechanical cable controls or the Yanmar VC10 electronic control system.

YANMAR 4LV HIGH POWER MODELS
Following last year's introduction of the 150, 170 and 195mhp engines in the new 4LV Series of common-rail engines, Yanmar is for the first time introducing the addition of the two highest power models - the 230 and 250mhp versions - to complete the five-engine range.

The 3800rpm-rated 230 and 250mhp models feature an increase in output and different turbo models from the first three 3500rpm units in the engine maker's mid-section range of leading diesels.

The new 4LV higher power engines have been designed for power recreational boating and small commercial craft applications. They incorporate the latest technology to enable extremely low vibration and noise levels for a smooth and quiet running engine, including a counterbalance shaft and refined component design, Yanmar adds.

Boasting a class-leading power-to-weight ratio, the 4LV delivers powerful low-end torque performance that results in "stunning acceleration" and, Yanmar says, really sets these engines apart from others in their power range.

NEW YANMAR JC20 JOYSTICK SYSTEM
Yanmar's common rail engine range is now complemented by a choice of proprietary controls, including Yanmar's new JC20 joystick system for easy manoeuvring solutions which is available from February 2018.

Designed to be easy-to-use, the JC20 enables precise joystick manoeuvring for twin straight shaftdrive engine installations in combination with a bow thruster.

Yanmar says its new joystick controller allows owners of motorboats, powerboats, and catamarans to dock accurately and smoothly by simply pressing the joystick in the desired direction. The JC20 automatically directs the speeds of the two engines and uses the thruster to precisely shift the boat.

The introduction of the JC20 completes Yanmar's joystick control line up, already featuring the 4JH80 SPP (Steerable Propulsion Pod) joystick manoeuvring system for large sailing yachts and the JC10 Joystick for twin sterndrive, all of which integrate directly with Yanmar engines
